Properties: NH4SCN,a colorless crystalline or column crystal that is soluble in water, methanol, ethanol, pyridine, acetone & ammonia and insoluble in ethyl acetate, methyl chloride and chloroform; at 140°C  bring  thiourea.  melts at 149.6°C. .thermal decomposition at 170°C may produce highly toxic fumes of hydrogen cyanide, hydrogen sulfide and toxic oxides of nitrogen, sulfur, and carbon.
Usage:
Genaral: Mainly in  pharmaceuticals, pesticide, textile,electroplating, photography,water tracer in oil fields, thinning agent, as intermediate for metal thiocyanates etc.
Textile:  printing, dyeing and finishing operations accelerator in fixing baths
Pesticide: raw material for the production of a number of herbicides and fungicides
Photographit: Stabilizer, accelerator, etc.
Metal finishing: Plating, flotation agent.
as intermediate for metal thiocyanates (NaSCN, KSCN, CuSCN, Ca(SCN)2 ).
Packing: 25kg each net, Kraft-plastic laminated bag with PE liner.   net 25kg woven bags.
Storage: Store away from incompatible substances. Keep in a tightly closed bags. Store in a cool, dry, ventilated area to prevent it from being deliquescent. Separated from acids, bases and oxidants.
